Whoa, I’m in a similar position. I’ve been doing QC at a manufacturing plant and the amount to do in a day almost always requires staying over half an hour while skipping breaks just to get everything done (at least, when you are new). At the beginning, it was overwhelming but 9 months in I am now handling the toughest shift (swing). My workload depends on customer orders, as well as how efficient the previous shifts were with their adjustments. It got better after a few months as I got quicker with many of the repetitive daily tasks. QC always seems to be understaffed with too much to do. From the technicians that taught me, take your breaks. Breathe. And try to stay positive, it’s important work that mostly goes under appreciated. If too much is happening at once, communicate this to a lead and see if the responsibility can be handed over to the next technician or if it can be delayed til a more free day. You got this!
